This research introduces "gauge fields" to optimize relaxation spectra within Fokker-Planck dynamics, enabling precise control over convergence rates without altering a system's stable state. By mapping these operators to supersymmetric Hamiltonians and utilizing learned nonreversible forces, the study achieves significant improvements in spectral gap management for complex stochastic processes. The methodology offers direct implications for accelerating training in machine learning models that rely on gradient-based optimization techniques.

Gauge Fields Modify Spectra and Induce Currents in Fokker-Planck Dynamics

Quantum ZeitgeistJune 15, 20265 min read

Learned forces now optimise relaxation spectra in Fokker, Planck dynamics, recovering the Lyapunov-equation optimum where previous methods failed. This is achieved by formulating nonreversible perturbations as gauge fields, leaving the invariant state unchanged but altering the rate of relaxation. A double-well potential demonstrates constrained selection within complex energy landscapes.

Masayuki Ohzeki, Tohoku University, in collaboration with Kumamoto University, Japan Research and Education Institute, Sigma-i Co, and Institute of Science Tokyo, have identified a framework for introducing nonreversible forces into Fokker-Planck dynamics as ‘gauge fields’ that reshape the relaxation process without altering the final, stable state. The work establishes a connection between relaxation gaps, probability currents, and control costs through a unified operator viewpoint. A learning procedure optimises these forces, showing promise for applications ranging from accelerating convergence in complex systems to enhancing…
